LOS ANGELES >> The last suspect accused of setting the 1,952-acre Colby Fire will be tried this week.

The trial for 23-year-old Jonathan Jarrell is scheduled to begin Tuesday at a Los Angeles federal court.

The other two suspects in the case, 22-year-old Clifford Henry of Glendora and 21-year-old transient Steven Aguirre, were convicted Friday of setting fire to timber, grass and underbrush in the Angeles National Forest by building a campfire; violating a fire restriction order by using a fire outside a recreation site in the forest; causing timber, trees, brush and grass to burn in the forest without a permit; and causing and failing to maintain control of a Jan. 16 fire that damaged the national forest system.

Federal prosecutors said Henry and Aguirre face a maximum of 61/2 years at their Aug. 4 sentencing.

Jarrell, who is a transient, has been charged with the same four counts.

Five firefighters and one civilian suffered minor injuries during the Colby Fire which started Jan. 16 along the Colby Trail above Glendora. The massive fire also destroyed five homes and 10 outbuildings as well as damaged seven homes and one other structure, according to the U.S. Forest Service.

Investigators said Henry, Aguirre and Clifford started two illegal campfires while camping overnight along the Colby Trail. Embers and burning paper from the second campfire set nearby dry grass and brush on fire.

The blaze spread quickly. The three men ran. Aguirre and Henry ended up in a wash where a resident saw them and called police. The officer noticed they smelled of smoke, had ashes on their clothing and were acting nervous. Henry and Aguirre were arrested.

A U.S. Forest Service fire prevention technician driving up Glendora Mountain Road about 7:30 a.m. Jan. 16 saw Jarrell in the area where the Colby Trail intersects with Glendora Mountain Road.

Because of the danger posed by the fire, the technician offered Jarrell a ride out of the area. Investigators said the technician suspected Jarrell had something to do with the fire because of his close proximity to the origin of the fire,

Jarrell also allegedly made statements that further raised suspicions. He was arrested.
